CH EESE-VAT.

J'PECIFICATION forming part of Letters Patent No. 364,128, dated May 31, 188T7.

Application filed April 6, 1886. Serial No. 198,007. (No model.)

To all whom t may concern:

Beit known that I, ROBERT OLP, a citizen of the United States of America, residing at Manitowoc, in .the countyl of Manitowoc and State of Wisconsin, have invented certain new and useful Improvements in Cheese-'vata of which the following is a specication, reference being had ltherein to the' accompanying drawings.

This invention pertains to improvements in l cheese-vats, having for its object to divert the flame or heat from the milk-pan as the water is drawn off, to facilitate the feeding of the fueland the cleaning of the hre-box, and to effect the perfect straining and withdrawal of the whey; and the invention consists of the combination of parts, including their construction,substantially as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a plan View of my improved cheese-vat. Fig. 2 is a front elevation of the invention. Fig. 3 is alongitudinal section on the line .fr ne,l Fig. 1. Fig. 4 is a transverse section thereof, the latter section being taken through the hre-box on the line y y, Fig. 3. Fig. 5 is a detail view. Fig. 6 is a side elevation. Figs. 7 and- 8 are detail views of the valve and its conjunctive parts, and Fig. 9 is a sectional detail view of the damper and the adjoining parts.

In the organization of my invention I employ a receptacleA,' for holding the water to be heated in the operation of making cheese. This receptacle is preferably rectangular or oblong and is mounted upon legs a, one being affixed to each corner and at each side at the middle. It is provided with a metallic bottom,and has a series of heating-pipes B B, extending through it from end to end, the saine also extending through its ends and connected at their front ends to the fire-box C and at their rear ends to the smoke-box D, asl presently more fully disclosed. These pipes are set into and supported about centrally of their lengths upon a crossbar, b, firmly seated or secured in the receptacle A, the lower side of which cross-bar is provided with transverse recesses in it to permit ofthe unobstructed fiow of the water in the said receptacle.

The rebox O is, as before intimated, disposed at the forward end of the receptacle A,

having its front end secured to the said end of l the receptacle and projecting forward thereof to permit convenient access thereto. The fireboX is extended under the receptacle A about one-third the length of the latter, with its up- This fire-box is div into two chambers or compartments, C G2, the

lower chamber or compartment, G', of which forms the combustion-chamber, its front end projecting downward and in a plane forward of the upper compartment or chamber, G2. At A the front these chambers or compartments are provided with doors e e', hinged to the front edge or Vend of the .plate d', the upper one at its lower edge and the lower one at its upper edge. The upper door, c', is retained in itsv closed position by spring-clasps ff, fastened to the front top part of .the hre-box, the forward curved ends of which project beyond the front upper edge of said door, `while the lower door, e, retains its closed position by gravity and is provided with a draft-regulal tor, g, and ahandle, g', to permit the opening of the door. The lower door, e, of the lower compartment, C', of the tire-box C permits of the ready or convenient cleaning of the same of any light ashes or other products of com- L ulated by means hereinafter stated.

The combustion-chamber C is provided at the rear end with a plate, h, composed of serially-spaced-apart bars h', forming apertures between the same, and said plate is disposed in an inclined position, its lower horizontal edgebeing rigidly secured to the rear end of the said chamber C', near which point is also secured the lower end of the vertical portion of a right-angular plate, which conforms to the inner right-angular portion of the rear end of said fire-box. tion of this rightangular plate bears against the under surface of the partition or plate d and to its forward end is rigidly connected the upper forward edge of said apertured plate h. This right-angular plate i is provided in its horlzontal portion with three or more open- 1ngs or apertures, d2, and in its vertical or rear portion with a large opening or aperture, da, communicating with the flue E, as will appear farther on. Within the smoke-box D is arranged a small pan or receptacle, a, directly at that end of the smoke pipe or 'flue E, to catch and permit of the convenient removal of light ashes, soot, &c., the smoke-box havinga small door for the removal of the pan and its contents when required.

The combustion-chamber C and smokebox D are connected to a pipe or flue, E, upon the frame-work beneath the receptacle A.

Within the space formed between the walls of the right-angular plate i and apertured plate h is arranged a damper, I, in general outhnebeing of the sameformation as the right'- .angular plate t', against which it is designed to slide, and is manipulated by a rod, i', connected to said damper and having its inner short right-angularly-bent end extending through a suitable slot in the side of the firebox and the vertical portion of the plate i, and projecting along the rear end of said fire-box toone side of the receptacle, within convenient reach of manipulation to open or close the tirebox end of said flue or pipe E, as may be required. The horizontal plate of this rightangular damper I has formed therein openings or apertures d4, the same corresponding in number to the openings or apertures formed 1n the horizontal portion of the platev i, and the other or vertical plate of said damper has but 011e large opening or aperture, d, corresponding to the openipg in the end ofthe flue E and the vertical portion of the plate i. The openings d* in the horizontal part of the damper I are so arranged that when the opening or aperture in said damper registers with the flue E the openings or apertures in the horizontal portion of the plate z' are closed, and vice versant-hat is, when the openings or apertures d are registering with the said openings or apertures d2 the opening of the fine is closed. By the movement of said damper or plate I so as to open up communication between the combustiouchamber Gand the pipe or flue E, leading to the smokeebox D, the llame or heat will be diverted from the upper chamber, C2, and consequently from the waterheating pipes B, and conducted into said flue directly to the smoke-box, as is required when drawing or running off the water from the rel ceptacle A, the latter having a waste-water cock or faucet, j, at the front end, as well as a supply-funnel, k', at its rear end.

The water-heating pipesB are screw-thread- The upper horizontal por-l ed at their ends where they pass through the apertures in the upper compartment, C2, of fire-box C and the smoke-box D, and said screw-threaded ends of the pipes are connected to the ends of the receptacle A by means of bushings or nuts Z, one applied to each end of the pipes, and said bushings are each provided with ascrew-threaded rim or ring, l', screwing into a threaded aperture in each end of the `receptac1e,while directly through the center of the bushing or nut is a screw-threaded aperture, ZZ, into which screws the end of the pipe or flue.

The front or disk portion of the bushing or nut projects'by its rim or ring and rests against the outside of the receptacle. By means of this construction of bushing or nut and its connection with the pipe a water space or chamber, Z3, is provided intermediately of the pipe and the ends of the receptacle to prevent the scorch ing or charring of the wood of said ends.

F is a whey tank or pan,whicl1 is preferably' zinc-lined and adapted to fit snugly upon and partly within the receptacle A, having its upper outer portion resting at its lower edge upon the upper edge of the receptacle and connected thereto by hooks and eyes. Upon the under side of the bottom of the pan or tank- F are secured, suitably spaced apart, strips or slats e4, which re-enforee or strengthen the bottom.

The b'ottom of the pan or tank F slopes toward the forward end and the middle to drain oli the whey, while the front end of the pan or tank is provided with an outlet or opening, mf, in alignment with the vertex ofthe side-sloping surface ol' the bottom.

Arranged to work in the inner end of the outlet or opening m isavalve, G, whose inner surface or face is conical, fitting a corresponding inner surface of said outlet or opening, and whose stem G extends through the outlet or opening and some distance beyond the same. The portion of the outlet or opening m made directly through the pan or tank has a short nozzle, m', on the outside of the latter, which enters a pipe, mi, also forming a part of said outlet or opening, which pipe is screwed into and through the front of the receptacle A, and

is provided with a scrcw-threaded lateral discharge nozzle or outlet, m, to which is con nected suitable means for passing off the whey. The valve-stem G is provided near the valve with a disk-shaped strainer, G, (see Figs. 7 and 8,) to eect the straining of the whey as it is drawn 01T and within the pipe m2, and is provided with a Worm-like screw-thread, m, which engages or works in a corresponding female screw-thread, m5, in said pipe, to per mit the ready opening and closing of the valve G. The outer end of the pipe mz is also fitted with a caplike nut,-m6, limiting the inward movement ofthe valve-stem with its valve, and upon the outer end of the valve-stem is applied and held thereon, by aspline or feather, a handwheel, G3, or lever, to permit of the convenient operation of the valve-stem in opening and closing the valve.

The inward movement of the valve and its stem 1s limited, as above stated, by reason of the-wheel Gs coming in contact with the nut m6, screwed or fitted on the pipe mi, through which said valvestem passes.

To the front legs, a, of the receptacle A are applied supplementary legs or extensions cc, which are confined to and permitted to slide upon primary legs a by means of keepers or staples a, fastened to the latter legs and embracing the supplementary legs. The lower en ds of the supplementary legs a are provided w1th feet @somewhat thicker than the primary legs a, and to each of them is pivotedthe lower end of the stem of an approximately T-shaped lever, H, the cross piece or head of theT being curved, and forming an eccentric with its extremities slightly turned up, forming steps o o thereat.. The upper convexed surface of the cross pieces or heads of the levers H bear against the peripheries or faces of flanged frictional disks or wheels L, hung or revolving upon axes fastened to the legs a from their outs1des,the flanges of the wheels or disks serving as guards to prevent the accidental displacement or disengagement of the levers therefrom.

`To the stem or vertical portion of one of the levers H is Iixed in any suitable way a handle or lever, H2,\vhicl1 is retained in position,when.

released from the hand or out of action, by a bent or stepped spring-catch, h, as shown. In their normal positions (shown in Fig. 6) the supplementary legs a a will permit' the contrivanceor vat as a whole to stand level; but when it 1s desired to draw oft'v the whey and to effect the thorough draining of the whey tank or pan the handle or lever is grasped and disengaged from its catch, when the weight of the contrivance, pressing upon the primary legs a, will have the effect to transmit the pressure through the wheels or disks L to the eccentrally-eurved cross-pieces and stems of the levers H', which curved pieces will naturally move under the said pressure, carrying with them bodily the levers, thus permitting the sliding ofthe primarylegs a down on the supplementarylegs a,and consequently lowering that end of the contrivance, or disposing the samein a forwardlyinelined position,when the whey, to the last thereof, may be drawn off through the valves. The water, it will beunderstood, is drawn from the receptacle A by means ofthe hefore-referred-to cock or faucet j.-

In order to restore the vat or contrivance toits normal lor level position, it is only necessary Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1; The combinatiomwith the receptacle and its water-heating pipes located therein, of the lire-box having two chambers or compartments, one of said chambers or compartments extending up in front of the receptacle and communicatingv with saidpipes for heating the contents of said receptacle, and the other chamber or compartment communicating with a lue leading to a smoke-box arranged at the rear end of the receptacle, said fire-boxhaving a damper arranged to open andclose the said flue and to open and close the openings leading from the lire-box to the upper compartment thereof, substantially as shown and described.

2. The combination,with the receptacle, its water-heating pipes,'and the lue connecting with a rear smoke-box, of the lire-box having two compartments or chambers extending be- 1 lyond the front of said receptacle, and to one of which said flue is also connected, and the hinged doors secured at their upper and lower ends, respectively, tothe forward c nd of acentral partition of said re-box,- one of sai-d doors having a draft-regulating damper, substantially as shown and described.

3. The combination,with the water-receptacle, of the water-heating pipes arranged there in, the smokeand re boxes disposed at opposite ends of said receptacle, the smoke-ilueunderneath the receptacle, said water-heating pipes and flue connecting the re and smoke boxes, and the damper arranged within the fire-box to open and close alternately the tirebox end of the smoke-flue and the said water heating pipes, substantially as shown and described. Y

4. The combination, with the receptacle, of the devices for loweringfone end thereof, the same consisting of the supplementary legs, capable ofsliding or moving upon the primary legs, and the approximately T-shaped levers, with their lower ends pivoted to the feet of the supplementary legs and their upper ends provided with eccentrically-curved vcross-pieces bearin g against the disks or wheels on the primary legs,with means to actuate and release the said levers, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses. l.
